Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device such as a personal computer or a word processor having a rotatable display unit, which converts display contents according to the orientation of a display screen changed by rotation of the display unit. Data display method.

[0002]

2. Description of the Related Art Conventionally, by rotating a rotatable display unit having display screens having different aspect ratios, data which can be used as a portrait screen in which the display screen is installed in a portrait state or a landscape screen in which the display screen is installed in a landscape state is displayed. Processing devices are known. In this type, whether or not the display screen is installed on a vertically long screen or a horizontally long screen is detected based on whether or not the orientation of the display screen is in a predetermined reference state. That is, a detection switch for detecting that the display screen is in the landscape state is provided, and when the detection switch is on, it is detected that the display screen is installed on the landscape screen. I have. Alternatively, a detection switch for detecting that the display screen is in the vertically long state is provided, and when this detection switch is on, it is detected that the display screen is installed on the vertically long screen, and when the detection switch is off, it is detected that the display screen is installed on the horizontally long screen. I have to. That is, on the basis of either landscape or portrait, whether one of the display screens is vertically or horizontally installed is detected by turning on / off one detection switch.

[0003]

However, for example, when switching from landscape to portrait in a screen based on a landscape screen, the detection switch changes from on to off. Although it can be detected immediately, when switching from portrait to landscape, the detection switch remains off until the display screen is completely landscaped, and the switching detection is delayed by that much. Note that this is exactly the same in the reverse relationship even when the vertical screen is used as a reference.
By the way, the display content is converted into a format suitable for the orientation of the screen according to whether the display screen is in the portrait state or the landscape state. In this case, as described above, one of the switchings can be detected at the same time as the display unit is rotated, so that the display conversion process can be executed earlier. However, the detection of the other switching takes a long time.
The display conversion process has been delayed by that much, and has become very uncomfortable for the user. An object of the present invention is to change the orientation of the display screen by rotating the display unit, and when starting to rotate the display unit in any orientation, the display content is suitable for the orientation of the screen. That is, it is possible to start a display conversion process for converting the format.

[0004]

The means of the present invention are as follows. When rotating the display unit to change the orientation of the display screen, the start of rotation of the display unit is detected, and the orientation of the display screen before that is detected. The display conversion process for recognizing the orientation of the display screen after the change from the orientation and converting the display content into a format suitable for the orientation of the screen is started. The conversion result obtained by the display conversion process may be displayed when the orientation of the display screen is changed and confirmed. Further, when the display conversion processing is completed, the conversion result may be displayed. When the orientation of the display screen is detected at the time when the orientation of the display screen is determined, and the detected orientation of the display screen matches the orientation of the display screen before rotating the display unit, the display conversion is performed. The conversion result obtained by the processing may be invalidated. Therefore, according to the present invention, when the display unit is rotated to change the orientation of the display screen, the display content is changed to the orientation of the screen when the display unit starts rotating regardless of the orientation. A display conversion process for converting the data into a suitable format can be started.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a data processing device such as a personal computer or an office computer. In FIG. 1, the data processing device includes a CPU 1, a RAM 2, an input unit 3, a display unit 4,
Printing unit 5, storage device 6, storage medium control unit 7, storage medium 8
And a display rotation detecting section 9. CPU
A (Central Processing Unit) 1 is a central processing unit that controls the overall operation of the data processing device according to a program stored in a storage device 6.

[0006] The storage device 6 has a storage medium in which programs, data and the like are stored in advance, and this storage medium is constituted by a magnetic or optical storage medium or a semiconductor memory. The storage medium is fixedly provided in the storage device 6 or is detachably mounted. The storage medium includes a window system program, various application programs corresponding to the window system, a menu display program, and a printing process. A program and data processed by each processing program are stored. The program, data, and the like stored in the storage medium may be configured to be received and stored from another device connected via a communication line or the like. A storage device provided with the above storage medium may be provided on the side of the device, and the program and data stored in the storage medium may be used via a communication line. The storage medium control unit 7 has a function as a storage medium driving device that drives and controls a storage medium 8 (for example, a floppy disk) shown in the figure. The storage medium control unit 7 drives the storage medium 8 in accordance with an instruction from the CPU 1 and issues a write instruction. Is input, the specified data is written to a specified storage area in the storage medium 8, and when a read instruction is input, the specified data is read from the storage medium 8, and is read from the RAM 2 or the storage device 6. Write to the specified storage area.

The input unit 3 has a key input device for inputting slip data and the like and a pointing device such as a mouse for inputting various commands. The slip data and the like input from the input unit 3 are taken into the CPU 1 and stored in the RAM 2. The data is written to the display memory 2-1 and displayed on the display unit 4.
The display unit 4 is a liquid crystal display device, a CRT display device, or the like, and has display screens having different aspect ratios. Here, by rotating the display unit 4, the operator can freely use the display screen as a portrait screen in which the display screen is installed in the portrait state or a landscape screen in which the display screen is installed in the landscape state by the rotation mechanism. Here, in the effective display area of the display screen, the aspect ratio is made different by making the maximum number of dots that can be displayed in the horizontal direction different from the maximum number of dots that can be displayed in the vertical direction. The display rotation detecting unit 9 detects the installation state of the display screen by mechanical or optical switch means using a changeover switch or an attitude sensor for detecting whether the display screen is installed vertically or horizontally, and the like. A detection signal is given to CPU1.

The RAM 2 has a display memory 2-1, a flag register 2-2, a work memory 2-3, a save memory 2-4, and the like. The flag register 2-2 has a display screen which is currently set in a vertically long screen. This is a register in which a flag indicating an installation state of whether or not the image is installed on a landscape screen is set. The work memory 2-3 is a memory for temporarily storing a conversion result obtained by a display conversion process executed when the installation state is switched. That is, when the orientation of the display screen is switched, the CPU 1 executes display conversion processing for converting the display content into a display format suitable for the orientation of the screen, and sets the conversion result in the work memory 2-3. The contents of the work memory 2-3 are written to the display memory 2-1 and output for display.

FIG. 2 conceptually shows the structure and function of the display rotation detecting unit 9. The display rotation detecting unit 9 has two micro switches SW 1 and SW 2 and one projection A. . The protrusion A is integrally formed on the inner side (the opposite side of the display screen) of a disk C concentrically fixed to one end of a rotating shaft (not shown). Then, with the rotation of the rotating shaft capable of rotating forward and reverse, the protrusion A moves while drawing an arc-shaped trajectory, and presses / releases the actuators of the microswitches SW1 and SW2 to cause the microswitches SW1 and SW.
Turn 2 on / off. The micro switch SW1 is a switch that detects that the display screen D is installed in a landscape orientation, and the micro switch SW2 is a switch that detects that the display screen D is installed in a portrait orientation. here,
The microswitch SW1 is provided on a horizontal line passing through the center of the disk C, and the microswitch SW2 is provided on a vertical line passing through the center of the disk C, and is disposed near and outside the disk C.

Next, a display operation at the time of business processing will be described with reference to a flowchart shown in FIG. A program for realizing each function described in this flowchart is fixedly stored in the RAM 2 in the form of a program code readable by the CPU 1 or is loaded from the storage device 6 into the RAM 2. . First, CP
U1 captures a detection signal from the display rotation detecting unit 9 to detect the installation state of the display screen (Step A1) and activates / deactivates the installation state flag in the flag register 2-2 (Step A1). A2, A3). That is, when the micro switch SW1 is set on the landscape screen as shown in FIG. 2A, the projection A pushes the operator of the micro switch SW1, so that the micro switch SW1 is turned on, but the micro switch SW2 is turned on. Turned off.
In addition, when the micro switch SW1 is turned off and the micro switch SW2 is turned on (see FIG. 2B) when the screen is set on the portrait screen. Further, when the projection A is located between the micro switches SW1 and SW2 as shown in FIG.
W2 is turned off. That is, by analyzing the detection signals (2-bit parallel signals) of the microswitches SW1 and SW2, it is possible to detect three states, that is, the display screen is in a horizontally long state, a vertically long state, or an intermediate state between them. If a landscape screen is detected, "1" is set in the work memory 2-3 to turn on the installation state flag (step A2). If a portrait screen is detected, "1" is stored in the work memory 2-3. 0 "is set to turn off the installation state flag (step A3).

During the execution of the business process (step A4), the rotation of the display unit 4 is started, and it is detected whether the display screen is being switched (whether the display unit 4 is moving) (step A5). In this case, the micro switches SW1, S
The detection is performed depending on whether W2 is turned off.
If it is not currently moving, the process returns to step A4 and normal business processing is continued. This business process is, for example, a slip input process or a form output process, and the processing result is output in a display format according to the orientation of the display screen. If the movement of the display unit 4 is detected during the execution of this business process (step A).
5), the CPU 1 deletes all display contents (step A)
6). In this case, only the screen is erased and the display memory 2-
1 is kept as it is.

Next, the CPU 1 refers to the flag register 2-2 and detects the installation state of the display screen before the movement (step A7). Here, if the screen before the movement is a landscape screen, it is recognized that this switching is a switch to the portrait screen, and the display content is changed from the landscape screen to the portrait screen.
The vertical conversion process starts (step A8). On the other hand, if the screen before the movement is the portrait screen, the current switching is recognized as switching to the landscape screen, and the portrait to landscape conversion process for converting the display content from the portrait screen to the landscape screen is started (step A1).
2). This conversion processing is, for example, a form in which the digit pitch and the line pitch are changed, or a horizontal form set in advance for a landscape screen or a vertical form set for a portrait screen is selected, and the display content is selected. The conversion result is written in the work memory 2-3 (steps A9 and A1).
3).

Then, a detection signal is fetched again from the display rotation detecting section 9, and it is checked whether the movement is completed depending on whether one of the micro switches SW1 and SW2 is turned on, and the apparatus stands by until the movement is completed (steps A10 and A1).
4). Here, when the completion of the movement is detected, the installation state after the movement is determined (steps A11 and A15). If the installation state before and after the movement is different, that is, if the screen is switched from the landscape screen to the portrait screen or from the portrait screen to the landscape screen, the installation state flag is updated (step A16), and the work memory 2-3 is updated. Display contents memory 2-
1 (step A17), and step A
The program proceeds to step S18, where the contents of the display memory 2-1 are displayed and output, and then the procedure returns to step A4. On the other hand, when the installation state before and after the movement does not change, that is, when the display unit 5 is returned to the original state without rotating by 90 °, the process proceeds to step A18, and the contents of the display memory 2-1 are displayed and output. . Therefore,
In this case, since steps A16 and A17 are skipped, the conversion result in the work memory 2-3 obtained in step A8 or A12 is invalidated, and the original display content is returned.

As described above, when the display unit 5 is rotated to switch the display screen from portrait to landscape or from landscape to portrait during the business process, both the micro switches SW1 and SW2 are turned off. 5 can be detected. In this case, the rotation start can be detected based on the detection signals from the micro switches SW1 and SW2 without adding a special mechanism, so that it is possible to suppress structural complexity. Then, the conversion process in step A8 or A12 can be started in synchronization with the start of rotation of the display unit 5. In this case, regardless of the orientation of the display screen,
The start timing of the conversion process (steps A8 and A12) is when the rotation of the display unit 5 is started. Then, when the orientation of the display screen is determined, the conversion result is immediately displayed and output. Therefore, in any case of changing the display screen from landscape to portrait or from portrait to landscape, the display contents are switched at the same timing. be able to.

(Second Embodiment) Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment, the conversion result obtained by the display conversion process is output when the orientation of the display screen is determined (when the movement completion is detected). In the second embodiment, the conversion result is displayed. The conversion result is displayed even before the movement is completed. FIG. 4 is a flowchart showing a display operation at the time of business processing, similarly to FIG. 3, and steps B1 to B5 are performed in FIG.
Since these are the same processes corresponding to steps A1 to A5, description thereof will be omitted.

If it is detected that the display unit 5 is being moved during the business process (step B).
5) The contents of the display memory 2-1 are transferred to the save memory 2-4 and saved, and all the display contents are erased (step B6). Here, the installation state before the movement is determined (step B7). If the screen is landscape, the horizontal to vertical conversion processing is performed (step B8). If the screen is vertical, vertical to horizontal conversion processing is performed (step B14). The conversion result is the work memory 2-
3 is the same as in the first embodiment described above (steps B9 and B15). When the conversion processing is completed, the contents of the work memory 2-3 are written into the display memory 2-1 (steps B10 and B16), and
Display and output the contents of the display memory 2-1 (step B
11, B17). In this state, it waits until the movement is completed (steps B12 and B18). When the movement is completed, the installation state after the movement is detected (steps B13 and B1).
9).

If the installation state before and after the movement is different, the installation state flag is updated (step B2).
0, B21), and returns to the business process (step B4). If the installation state before and after the movement does not change, the evacuation memory 2
-4 is returned to the display memory 2-1 (step B22), and the contents of the display memory 2-1 are displayed and output (step B23). Then, the business process (step B)
Return to 4).

The second embodiment configured as described above has the same effects as the first embodiment, and also has a display unit 5
The contents of the conversion result can be displayed and output even during the movement of. In this case, the display content can be switched at the same timing regardless of whether the display screen is changed from portrait to landscape or from landscape to portrait.

In the above-described first and second embodiments, the display rotation detecting section 6 is constituted by the two micro switches SW1 and SW2 and the one projection A. The present invention is not limited to this, and may be arbitrary, and may be configured by one three-point switch SW3 and two protrusions A and B as shown in FIG. That is, the three-point switch SW3 is provided on a horizontal line passing through the center of the disk C, and detects a state in which the operating element is pressed downward in the drawing and a state in which the operating element is pressed upward. In addition to the contact, the actuator has a contact for detecting the intermediate state, and the operating element is restored to the normal intermediate state by receiving the elastic force of the spring. One of the projections A and B is a disk C
Are provided on a horizontal line passing through the center of the disk C, and the other is provided on a vertical line, and are integrally formed inside the disk C (the opposite side of the display screen). Then, the projections A and B move while drawing an arc-shaped trajectory in accordance with the rotation operation of the rotating shaft capable of normal and reverse rotation, and switch the three-point switch SW3.

In this case, FIG.
This shows a state in which the operator of the point switch SW3 is pressed downward. At this time, the three-point switch SW3 detects that the display screen is installed horizontally. FIG. 5B shows a state in which the operator of the three-point switch SW3 is pressed upward by the projection B. At this time, the three-point switch SW3 detects that the display screen is installed vertically. As described above, when the display unit 5 starts rotating in the state of the landscape screen or the portrait screen, the operation of the three-point switch SW3 is returned to the intermediate state by the restoring force of the spring. it can.

The display rotation detecting section 6 is not limited to a configuration in which a switch and a projection are combined, but is a combination of optical means, for example, a combination of a light emitting element and a light receiving element, and a slit formed in the periphery of the disk C. Is also good. Further, a detecting means for detecting the rotation amount is provided. For example, if the rotation amount is set to “0” for a landscape screen and the rotation amount is “90” for a portrait screen, the rotation amounts are “0” and “90”. , The intermediate state (moving) may be detected.

[0022]

According to the present invention, when the display unit is rotated to change the orientation of the display screen, the display content is displayed on the screen when the display unit starts to be rotated in any orientation. Since the display conversion process can be started to convert the display into a format suitable for the orientation of the display, the display contents can be switched at the same timing, and the proper display that does not give the user a feeling of discomfort unlike the conventional display Control becomes possible.
